.Net 4.0 DataGrid Control Horizontal ScrollBar Issue

I'm using .Net 4.0 DataGrid control to display my data using databinding. The data are displayed correctly but there is an issue with the horizontal scrollbar:

My datagrid has 15 columns and window when displayed is not showing all the 15 columns. This is okay as the window width limit the number of visible columns. So, as not all columns are visible, there is a horizontal scroll bar. If I drag the horizontal scroll
bar at once to the right of the datagrid, it will appear to be moved to the end right but it really go just to the middle. So even If moved the horizontal bar to the end right, it did not go all the way ! I was expecting it to go all the way.

If I keep dragging the horizontal scroll bar to the right until it reach the end, at that time, the scroll bar works properly. I can then move it to the left, and move it to the right end and this time it will go all the way.

Is this is a known issue ? Any workaround so the scroll bar go all the way to the right when dragged to the complete right ?

Important detail: I'm using columns virtualization (EnableColumnVirtualization="True"). If i turn off the columns virtualization, the issue

Using VS2010, I created an ASP.NET 4.0 web application and simply added a couple of menu items below the "Home" menu item in the master page that's created by the project wizard. I made no other changes - no code, no stylesheet changes.

If I run the app locally then everything is fine. I suspect because the local IIS is responsive enough for the problem not to occur.

If I deploy the app to a web host (discountasp.net) then I see the menu render vertically for less than a second before it renders correctly. If I refresh the page a few times then usually I can see the menu vertical flash but sometimes I can't, so there's some sort of timing consideration.

I'm using IE8. The problem doesn't seem to occur with either Firefox 3 or Chrome.

I hope you can help me, I tried Google, but none of the solutions worked. Using VB.net and Membership, I have a login control in my master page with a remember me check box. When I check this box and login, some pages indicate that I am not logged in. If I go to another page, it will then indicate that I am still logged in. I have isolated one page that always indicates I am not logged in the first time I visit it, but if log in a second time and then go to it, it will finally recognize me as a user that is properly logged in.

Some pages that this occurs on is in the top level, some pages are in a sub folder.

My MasterPage has the following Form Code:

<body bgcolor="#E0ECF9" topmargin="0" leftmargin="0">

<form id="form1" runat="server">

My Aspx file has a troubleshooting label, several Gridviews and several DetailViews:

Hello. I have a Repeater control which contains asp:Button control in ItemTemplate. I want to handle Button's Click event, but when I'm clicking that Button the error is thrown: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.But on other computer that piece of code is working.I set EnableEventValidation to false, but it's still not working. Please help me out.

Ok, everyone knows that the z-index is messed up in IE8 and that requires patches or workarounds...What I can't seem to find a solution to is the white background on the DynamicMenu parts of a Menu control. Setting the background color to transparent or not setting it all doesn't seem to have any effect. This is only a problem in IE8, Firefox 3.6.8 renders the dynamic menus without the white background.

I have a simple window with 2 tabs, and 4 datagrids. I set up each one with similar, if not identical settings. They all get their own DataSet based binding, and have standard Text columns, and combo box columns. Recently (past week) of
development, while I was adding filtering/sorting/grouping features to my program, the column widths have begun to ingore my settings. By collapsed I mean approx 20 pixels wide (just enough for the sorting Icon).
Contacts datagrid, works great in run time, but in design time the columns are all collapsed.
ContactsToClients data grid has no abnormal issues
Clients datagrid AND Clients to Contacts datagrid look great in design time, but show collapsed columns in run time.
How do I hunt down the problem? I've tried removing all the temporary code, and rebuilding, closing Visual Studio and reopening. I've remmed out the sorting code. None of these have any affect. It appears that my settings are all
being ignored. Here is the XAML code:

I'm using VWD 2010 Express, and I'm working on a school lesson that I actually did approximately 2 years ago In VWD 2005 with no problems. I am just learning to program, so my knowledge is very limited.The lesson walks me through creating a master page and then I created a page called "Login.aspx". On the login page, I am dropping a LoginView control into the ContentPlaceHolder section, and then I'm supposed to type "Welcome !" into the LoginView box for the LoggedIn template, but the LoginView box is very small and when I start typing, the first couple of letters go into the LoginView box, and then they start showing up on the far left outside of the LoginView control. When I try to click back in the LoginView window, it will only select the entire control, and I can no longer modify what's in the box (unless I go to Source view). I can't even begin to explain how frustrating this is!!! It's tough enough trying to learn this stuff and now my development tool is giving me grief! I don't understand why it worked fine in VWD 2005, but not now (and I'm using the same exact lesson material).

I've been investigating DataGrid for my embedded application. Basically, what I want to do is to read in information from my embedded system over USB. Store the information in a structure. And, retrieve the information from the structure
to display to the user. The information I want to display is an ID Number (1-255), an ID Description, and a Relay Number. The Relay Number is a drop down combo box with 4 options of 1-4, which is editable by the user. The ID Number
is not editable and the Grid should contain information all 1-255 IDs. The Description should be a maximum, editable, field of 30 characters (I might change later). Is the DataGrid the best way to do this?
I tried to implement a DataGrid (see below), but am having some problems getting the data into the columns correctly. Do I need both the Header entries in WPF and in the code? When I do, I get two columns of 'ID #' and 'IDNum' with 1-255 in each
column. I don't want the header 'IDNum', only 'ID #' as stated in the WPF code. I'm missing something. Maybe someone can help. Thanks.

I have a report (using SSRS 2005) which displays both the vertical scrollbar and horizontal scrollbar. The report has lots of columns.
The problem is that the horizontal scrollbar is only half displayed (height wise). I've tried resizing the report window but it doesn't change how much of the horizontal scrollbar is displayed.
I've tried playing with the report settings (margins, body size, etc) but can't seem to get the entire horizontal scrollbar to be visible. The users don't like this because the viewable part is hard to grab onto to scroll.
How do I fix this?
Thanks,
John

In IE8, while selecting the item in the dropdown list, the control goes out of focus immediatley when clicked for the list of items to select.It makes very hard for the user to select the value from dropdown list.

This dropdown control has some CSS settings enabled for it. I am not sure if this is an issue.

I have a DataGrid control on a form and I'm binding it to an ArrayList that is populated dynamically as the user scrolls. The array list is pre-populated with blank records equal in number to the number of records in the DB. As the user scrolls,
if they stop in a place where there are blank records I populate that data from the DB. I'm using the VisibleRowCount and VertScrollBar.Value properties to determine where I am in the DataGrid.

The problem is that if I scroll to the bottom of the control then maximize the control it's resize event fires, the VertScrollBar is redrawn proportionally to the number of records, but the Value and VisibleRowCount remain unchanged. If I then grab
and scroll the scroll bar up then back down to the bottom, the Value and VisibleRowCount update correctly. Is there a way for me to get these values some other way or to force the scroll bar to refresh/update manually?
